AIM： To investigate the correlation between expression of CD58 and severity of hepatitis B. METHODS： The level of soluble CD58 （sCD58） in serum of patients with hepatitis B was detected by enzymelinked immunosorbent assay. The level of expression of membrane CD58 molecule in PBMC was detected by direct immunofluorescence. The levels of serumal TBIL, DBIL, IBIL, ALT and AST were detected by the automated biochemistry analyzer as well. RESULTS： The levels of sCD58 in serum and membrane CD58 molecule in PBMC of patients with hepatitis B were significantly higher than that in normal controls （P 〈 0.05）. Level of CD58 was related to the levels of serumal TBIL, DBIL, IBIL, ALT and AST. CONCLUSION： The level of CD58 molecule （in both serum and PBMC form） of patients with hepatitis B is related to the degree of liver damage.

Toxicities of CdSe and CdSe/CdS quantum dots （QDs） synthesized by ultrasound-assisted methods were investigated in vitro and in vivo. Five human cell lines were used to assess the cytotoxicity of as-prepared CdSe and CdSe/CdS by assays of MTT viability, red blood cell hemolysis, flow cytometry, and fluorescence imaging. The results show that these QDs may be cytotoxic by their influence in S and G2 phases in cell cycles. The cytotoxicity of QDs depends on both the physicochemical properties and related to target cells.

In shallow groundwater agricultural fields, water exchanges between groundwater and soil water happen frequently and intensively. This paper analyzes the regale of subsurface water during the growing period of winter wheat from October 1998 to June 1999 in Yucheng area. During an 8- month period of winter wheat growth. 456.66 mm of evapotranspiration and 75.61mm of groundwater evaporation were measured with a new model lysimeter. Groundwater at 1.60-2.40 m depth of water tables contributed 16.6% of total water used by winter wheat under natural. precipitation and irrigation *** results showed that a significant proportion of field evapotranspiration was supplied by groundwater evaporation, whereas the role of groundwater evaporation was not considered during irrigation, leading to soil water percolation into *** order to improve water use efficiency of crops, some measures were put forward in the paper. Effective use of groundwater and soil water is a key countermeasure for sustainable development of water-saving agriculture and Water resource exploitation in Yucheng area

We report a novel cyano migration-mediated radical-polar crossover process, whereby both the sulfonylcyanation of aliphatic alkenes and the formation of cyclopropanes are concurrently achieved. This transformation yields a diverse array of multisubstituted cyclopropanes under mild photocatalytic conditions. Mechanistic studies elucidate that the reaction proceeds via intramolecular nucleophilic substitution, leading to the formation of the cyclopropane derivatives.

With the development of quantum computing technology, quantum public-key cryptography is gradually becoming an alternative to the existing classical public-key cryptography. This paper designs a quantum trapdoor one-way function via EPR pairs and quantum measurements. Based on this, a new quantum public-key cryptosystem is presented, which offers forward security,and can resist the chosen-plaintext attack and chosen-ciphertext attack. Compared with the existing quantum public-key cryptos,eavesdropping can be automatically detected in this new quantum public-key cryptosystem under a necessary condition, which is also detailed in the paper.
